Umgangatho oPhezulu oPhakamileyo oqhelekileyo weDizili Isitofu seDizili 0 445 120 083 I-Diesel Fuel Injector 0445120083

Inkqubo yamafutha yinxalenye engundoqo ye-injini ye-diesel kwaye inoxanduva lokutofa i-fuel kwigumbi lokutsha ngoxinzelelo oluchanekileyo kunye nexesha elifanelekileyo. Impompo yokutofa kunye ne-injector zizinto eziphambili zenkqubo.

Okokuqala, indlela yokulungisa ukusilela kwempompo yokutofa kwamafutha. Iimpazamo eziqhelekileyo zibandakanya ukunxiba i-plunger, ukutywinwa kwevalve yokuhanjiswa kwe-oyile akuqinile, njl.njl Ngexesha lokugcinwa, i-plunger kunye nevalve yokuhambisa i-oyile kufuneka ihlolwe ngononophelo kwaye itshintshwe xa kukho imfuneko. Impompo yokutofa ngamafutha yetrektara ethile yezolimo ayiphumelelanga, nto leyo ebangele ubunzima ekuqaliseni injini yedizili kunye nokunciphisa amandla. Emva kokuhlolwa, kwafunyaniswa ukuba i-plunger yepompo ye-injection ye-fuel yayigugile kakhulu kwaye i-valve yokukhupha i-oyile ayizange ivalwe ngokuqinileyo, okubangele ukunyanzeliswa koxinzelelo lwepetroli kunye nokunikezelwa kwamafutha angalingani. Sebenzisa isivavanyi soxinzelelo lwepetroli ukulinganisa kwaye ufumanise ukuba uxinzelelo lwamafutha luyaguquguquka kuluhlu lwe-15 ukuya kwi-20MPa. Ke ngoko, buyisela i-plunger egugileyo kwaye ulungise indawo yokutywina yevalve yokuhambisa ioyile, kwaye usebenzise izixhobo ezikhethekileyo zokugaya ukugaya i-valve yokuhambisa ioyile ukuqinisekisa ukusebenza kwayo kokutywinwa. Emva kokutshintshwa, uxinzelelo lwamafutha luzinzile ngaphakathi koluhlu lwe-22 ukuya kwi-24MPa. Emva kokulungiswa, injini ye-diesel yaqala kakuhle, amandla abuyele kwisiqhelo, kwaye izinga lokusetyenziswa kwamafutha liye lancitshiswa kakhulu.

Okwesibini, indlela yokulungisa iimpazamo ze-injector. Iimpazamo eziqhelekileyo ziquka imilomo evaliweyo, i-valve yenaliti ebambekileyo, njl. Ngexesha lokugcinwa, i-injector idinga ukuchithwa, ukucocwa kunye nokulinganisa. Isitofu senjini yedizili yenqanawa ethile ayisebenzi kakuhle. I-injini ye-diesel ikhupha umsi omnyama kunye nokwandisa ukusetyenziswa kwamafutha xa isebenza. Emva kokuqhaqha i-injector ye-fuel, kwafunyaniswa ukuba kukho i-carbon accumulation enzima ngaphakathi kwi-nozzle, ekhokelela kwi-atomization ye-fuel embi. Ibhentshi yokuvavanya i-fuel injector yasetyenziselwa ukuvavanya, kwaye kwafunyaniswa ukuba umthamo we-injection ye-fuel wawungalingani kwaye umphumo we-atomization wawungalunganga. Sebenzisa i-agent ekhethekileyo yokucoca ukucoca i-carbon deposits ngaphakathi kwi-nozzle, kwaye ugaye i-valve yenaliti ukubuyisela ukuguquguquka kwayo kunye nokutywinwa. Emva kokucoca, kwavavanywa kwakhona kwibhentshi yokuvavanya. Isixa senaliti yepetroli sasilinganayo kwaye isiphumo se-atomization saphuculwa kakhulu. Emva kokugcinwa, umsi omnyama waphela xa injini ye-diesel isebenza, kwaye izinga lokusetyenziswa kwamafutha libuyele kwisiqhelo.
